WATERTOWN, Mass. -

David Henneberry calls himself an "incidental hero."

The Watertown man, who found Boston Marathon bomb suspect Dzhokhar Tsarnaev hiding in a boat in his backyard ending a week of terror for the region, told NewsCenter 5's Ed Harding exclusively that his one hope is to bring closure to the families of those killed and those who were wounded.

"I'm just glad," Henneberry said as he struggled to control his emotions. "I hate to use clichés. If people who were killed can get some (comfort), then I am at peace with it. If I help these people that lost people, if I can help them in their mind, then everything is good with me here."
